l .prising parallel Walls are employed as guid cording to my inventiononlyffiztn automatic change'of the degree of reaction in the variouslstages occurs, and the best. ratios of eripheral velocity to theab'solute inlet veocity can still(v be maintained.

" When ordinary guiding apparatus coming device the turbine itself maycomprise say 4 6 stages, and when conically expanded. Inozzles areemployed as guiding device the turbine will comprise say 2-4 stagesaccord-y ing in. each instance to the further employment of the outletvelocity fromfthe roto'n'lfi or not. Analogously same holds good withthe changed numbers in question for every other elastic medium, e. g.gals, ail' or the like, sind likewise for turbines having nozzles andblades rotating in opposite di..

ireotions and; particularly, for unipolar turbines'.

What I claim as newend desire to securev by Letters Patent is:

turbine of the character' described, comprisingin-combination a casing,divided into a selected number of stages, and a rotor proportionetedimensions selected in such :il manner that the relative entrancevelocity of 'the fluid into thebuckets of seid rotor .is equal to .the'so-called .criticalvelocit Ysubstentielly as described. x
